I have Whole Home Premium, 3 discs, one connected to router. Of the 3 (not the master) one seems to periodically freeze every few days, it shows as blue in the app and says its working, it has a blue light light on but the devices connected to it are not accessible. I restart the disc via the app and it all starts to work ok after a few minutes. This is only just started to happen in the last 2 to 3 weeks, over the previous 6 months absolutely no issues.
